Long story short I purchased a 2023 GLE 450 on the salvage auction. It did not start because of airbags and 12V battery was drained. I bought a new battery and replaced the airbag pyro fuse and it still does not start. I am getting 2 codes for the 48V battery. I am assuming it is completely drained as well from sitting for some time. The codes I am getting are: U029987 and U029900. Any help and guidance would be much appreciated.

Battery BMS probably went into a lock mode after the "crash." You'll have to reset it somehow or buy a new one.
